Cygnus cygnus – ALARCH GOGLEDD – Scarce winter visitor and passage migrant
Mathew (1894) noted only undated records from Pant y Phillip and one shot by Lord Cawdor at Stackpole. Lockley et al. (1949) cited a flock at Cosheston from 24 to 28 January 1933, which had moved to Garon Pill by 29 January, and a pair at Dowrog Pool on 26 January 1948.
Up to 20 birds per annum were recorded in 31 of the next 42 years, none staying for longer than a few days, apart from one that was at Marloes Mere from 7 December 1991 to 25 January 1992. Most occur between December and February but there is evidently an erratic through passage in October to November and March to May, the largest group recorded being 47 which flew over Skokholm on 19 February 1956.
